Hydroxymethylfurfural oxidation over unsupported Pd-Au alloy catalysts prepared by pulsed laser ablation: Synergistic and compositional effects

Noble-metal high-entropy-alloy tuning the products of electrocatalytic 5-hydroxymethylfurfural oxidation

“…16 Moreover, other results reveal that Pt and Pd are capable of being fine-tuned through alloying to optimize the adsorption energy of HMF by regulating the d-band center. 13,25,28,29 For example, the AuPd alloy exhibited remarkable efficiency in facilitating the aerobic oxidation of HMF to FDCA in an aqueous environment under mild reaction conditions with complete conversion of and 99% yield of FDCA. 25…”

PLLA Nanosheets for Wound Healing: Embedding with Iron-Ion-Containing Nanoparticles

“…The produced NSs were characterized, and their ability to release Zn ions was tested after immersion in water at pH of 7.4 and 37 °C [11]. To prepare such Zn-containing NPs, we applied laser ablation in liquid (LAL) phase, which is a convenient laboratory technique to prepare diverse nanomaterials (including metallic and metal oxide NPs, among others) with easy parameter control and at laboratory scale [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] (see Figure 1). Encouraged by the previous results, herein we apply the same method to produce Fe-containing NPs as nano-reservoirs for Fe ions that can be released from their PLLA matrix (NSs) upon embedment.…”

Effect of K+ and Ca2+ Cations on Structural Manganese(IV) Oxide for the Aerobic Oxidation of 5-Hydroxymethylfurfural to 2,5-Furandicarboxylic Acid

“…In the current research regime of FDCA production, heterogeneous catalysts have been more attractively developed due to the stability and reusability. The oxidative catalytic methods have been extensively studied in various process of noble metals [gold (Au), , palladium (Pd), platinum (Pt), rhodium (Rh), and ruthenium (Ru) and non-noble metals [cerium (Ce), cobalt (Co), iron (Fe), and manganese (Mn) − ] supported heterogeneous catalysts. Moreover, the nonbase oxidation of HMF was studied over the Co–Mn–Br catalysts to produce high yield of FDCA. − Interestingly, a promising nonprecious manganese oxide (MnO 2 ) could act as an effective heterogeneous catalysts for the aerobic oxidation of HMF to FDCA in which the catalytic performance was determined by the oxygen vacancy formation. , Recently, calcium manganese oxide has been taken as an inspiration to achieve the goals of biomimetic oxygen-evolving catalysts and organic sulfide oxidation. − Although the calcium manganese oxides have been used to support of Pd nanoparticles (PdNPs) in HMF oxidation, their catalytic properties of bare support materials remain a challenge in this field to reveal the synergistic interactions .…”
